Question

two angles in a triangle are in the ratio 4:6.If the sum of these angles is equal to the third angle,then what is the value of the third angle

Answer 1

let, the given angles are
4x and 6x.
third angle= 4x+6x=10x (given in question)
so, by the angle sum property of the triangle,
4x+6x+10x=180
20x=180
x=180/20
x=9.
third angle=10(9) =90°
